interesting API! if you wanted to make this code even more object-orientated, you could move this define this entire conditional section as a method in the `Person` Class:

```ruby
class Person
  require 'rest-client'
  ...
  # this method will return true or false based on whether the person's age is zero or not
  def has_real_age?
    age != 0
  end

  def number_api_fact
    RestClient.get("http://numbersapi.com/#{age}")
  end
end
```  

and then in your `runner.rb` file:

```ruby
if new_player.has_real_age?
  puts new_player.number_api_fact
else
  puts "Use numbers, stupid!"
end
```
